On s\u2019int\u00e9resse en<br \/>\nparticulier aux pompes \u00e0 vide destin\u00e9es aux fondeurs de puces \u00e9lectroniques. Leur maintenance est<br \/>\ncruciale et doit \u00eatre r\u00e9alis\u00e9e avec un niveau maximal de s\u00e9curit\u00e9 et de confidentialit\u00e9, les arr\u00eats de<br \/>\nligne de production pour cause de panne non anticip\u00e9e impliquant des co\u00fbts tr\u00e8s importants. Dans<br \/>\nune infrastructure, les pompes sont compl\u00e9mentaires et organis\u00e9es en clusters. Elles sont<br \/>\ninstrument\u00e9es et associ\u00e9es dans un contexte IoT. A ce jour, malgr\u00e9 l\u2019exp\u00e9rience acquise, aucun<br \/>\nmod\u00e8le de pr\u00e9diction de panne traditionnel ou par apprentissage automatique ne permet de planifier<br \/>\nefficacement le retrait d\u2019une pompe \u00e0 vide avant sa d\u00e9faillance. Le probl\u00e8me sous-jacent est<br \/>\nfortement non lin\u00e9aire, doit int\u00e9grer des donn\u00e9es h\u00e9t\u00e9rog\u00e8nes et les mod\u00e8les ne g\u00e9n\u00e9ralisent pas face<br \/>\n\u00e0 la diversit\u00e9 des situations. Dans ce contexte, la th\u00e8se propos\u00e9e porte sur l\u2019apprentissage f\u00e9d\u00e9r\u00e9 dans<br \/>\nune infrastructure de communication pair \u00e0 pair. Ceci permet de r\u00e9pondre \u00e0 certaines contraintes de<br \/>\nconfidentialit\u00e9 et d\u2019apprentissage collaboratif int\u00e9grant des processus d\u2019adaptation locaux. D\u2019un point<br \/>\nde vue op\u00e9rationnel, ce type d\u2019approche permet de r\u00e9duire les interventions d\u2019experts humains sur<br \/>\nchaque mat\u00e9riel et d\u2019optimiser la gestion globale. Les questions scientifiques sont nombreuses et<br \/>\ns\u2019inscrivent dans un projet plus large. Celles \u00e9tudi\u00e9es dans cette th\u00e8se sont : (1) L\u2019identification de<br \/>\nmod\u00e8les de d\u00e9tection d\u2019anomalie pertinents pour des ensembles de mat\u00e9riels pr\u00e9sentant de<br \/>\nnombreuses d\u00e9clinaisons, usages et contextes, et (2) l&rsquo;apprentissage collaboratif (f\u00e9d\u00e9r\u00e9) dynamique<br \/>\npour la d\u00e9tection d&rsquo;anomalie sur un parc d\u2019appareils compl\u00e9mentaires.<\/p>\n<p><strong>Mots-clefs<\/strong> : anomalies, f\u00e9d\u00e9r\u00e9, s\u00e9ries temporelles<\/p>\n<p><strong>Publications :<\/strong><\/p>\n<p><strong>Encadrant<\/strong> : Alexandre Benoit<\/p>\n<p><strong>Co-encadrant<\/strong> : Olivier Passalacqua, Mickael Bettinelli<\/p>\n<p><strong>D\u00e9but de la th\u00e8se<\/strong> : Juin 2024<\/p>\n<p><strong>Ecole doctorale : SIE<\/strong><\/p>\n<\/div>\n<p class=\"bodytext\">\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Doctorant, Polytech Annecy-Chamb\u00e9ry.
